On an unusual day in September 2025, financial headlines around the world lit up with a surprising announcement: Larry Ellison, founder of Oracle, had become the richest man on Earth, overtaking Elon Musk with a net worth of approximately $393 billion. It was a moment of triumph for a man who had spent decades in the shadow of tech giants—but the celebration didn’t last long. Just hours later, Musk reclaimed the top spot thanks to a surge in Tesla and SpaceX shares, fueled by new AI launches from his company xAI.
Still, Ellison’s brief rise wasn’t a fluke. It was the result of strategic shifts within Oracle, especially in cloud infrastructure designed for training large AI models—making him a serious contender in the billionaire race.
Who Is Larry Ellison? A Life Unlike Any Other
Lawrence Joseph Ellison was born on August 17, 1944, in New York City to a single mother. He was adopted by his aunt and uncle in Chicago, where he grew up in modest conditions. His childhood wasn’t easy—he was raised in a working-class neighborhood, facing social and economic challenges. Yet from a young age, he showed an independent spirit and a deep curiosity for knowledge.
Ellison never completed college, dropping out of both the University of Illinois and the University of Chicago. But he discovered a passion for programming and technical work, starting his career at companies like Ampex, where he contributed to a database project for the CIA.
In 1977, he founded a small company called Software Development Laboratories, which later became Oracle, inspired by a research paper on relational databases. Under his leadership, Oracle grew into one of the world’s largest software companies, especially in databases and cloud services, competing fiercely with IBM and Microsoft.

His Management Philosophy: No Room for Weakness :
Ellison is known for his sharp management style. He doesn’t believe in workplace niceties and encourages internal and external competition. In one of his quotes, he said: “If you’re not prepared to fail, you’ll never succeed.” He favors fast decision-making, relies on intuition backed by data, and believes innovation comes from bold execution—not endless meetings.
Despite his tough persona and bold decisions, Ellison is famous for his love of luxury. He owns lavish yachts, private jets, and even purchased an entire Hawaiian island called Lanai, where he lives a secluded, eco-conscious lifestyle and oversees private tourism and sustainability projects.
He’s also active in philanthropy, having donated hundreds of millions to medical research, especially cancer treatment, and funded research centers at the University of Southern California—proving that for him, success must leave a human impact.
How Oracle Reclaimed the Spotlight in the AI Era
In recent years, Oracle—under Ellison’s direction—has focused heavily on cloud infrastructure, targeting startups and tech giants developing AI models. The company signed major deals to provide high-performance computing services, positioning itself as a direct competitor to Amazon AWS and Google Cloud.
This strategic pivot led Oracle’s stock to surge by over 40% in just weeks, directly boosting Ellison’s net worth, as he owns more than 40% of the company’s shares.
Ellison’s Key Investments in Artificial Intelligence
Ellison didn’t stop at building Oracle’s cloud backbone. He pushed the company to form strategic partnerships with emerging AI firms like Cohere and Anthropic, offering secure and scalable environments for training large language models. Oracle also invested in advanced data centers powered by NVIDIA H100 chips to meet the growing demand for AI-specific computing.
These moves made Oracle a foundational player in the infrastructure behind AI development—explaining the sudden spike in its market value and Ellison’s wealth.
How AI Is Reshaping the Billionaire Rankings

Artificial intelligence has evolved from a promising technology into a powerful force reshaping global wealth. It’s no longer just about the companies building AI models—it’s about the infrastructure that powers them: data centers, cloud platforms, and specialized chips.
Larry Ellison is a prime example of this shift. While others focus on developing the models themselves (like GPT or Claude), Ellison invested in the core layer that makes those models possible—high-performance cloud infrastructure. Oracle signed massive contracts with AI startups to provide cutting-edge training environments, placing the company at the heart of the global AI ecosystem.
📊 Real-world examples of this trend:
In 2023, OpenAI’s Sam Altman saw his influence rise after partnering with Microsoft, despite owning little equity.
In 2024, NVIDIA’s stock soared due to demand for AI chips, propelling founder Jensen Huang into the world’s top 30 richest people.
In 2025, Ellison briefly topped the billionaire list—not by launching a new AI model, but by enabling the infrastructure that made those models possible.
This shift raises a key question: Has AI become the new standard for building extreme wealth? The answer is clear: yes—but not just for those creating the models. The real winners are those who own the infrastructure, the computing power, and the ability to scale globally.
Could Ellison Become a Permanent Contender for the Richest Title?
That depends on two major factors:
Oracle’s continued growth in the AI infrastructure market If more companies rely on Oracle’s cloud services to train their models, the company’s value will keep rising—along with Ellison’s net worth.
Volatility in Tesla and SpaceX stock Musk’s wealth is tied to highly volatile assets, which opens the door for rivals like Ellison to briefly take the lead during market shifts.
What’s certain is that Ellison is no longer just a name on the billionaire list. He’s now a central figure in shaping the future of artificial intelligence—especially in the invisible infrastructure that powers it all.
